Tombak (also Tonbak, Dombak, Donbak or Zarb, Persian) is a Persian, goblet-shaped hand drum, which is the main percussion instrument of Persian folk music as well as of classical Persian music.
The body of the Tombak was formerly carved mainly from solid mulberry wood. The upper, wide opening is covered with animal skin, usually of camel, goat or calf. The tuning-mood depends on air humidity and can therefore only be affected by moistening or heating (drying the skin).
The Tombak I have developed is composed of several pieces of wood glued together, which have then been hand-turned. It is usually covered with goatskin and tunable by either a screw system or a rubber tube system.
Since my Tombak consists of several individual parts, it will maintain its shape and not warp over the years.
